Abstract (en)

[origin: EP0952113A2] A water treatment assembly receives water from a car wash for processing and re-use. The novelty is that: (a) the used water is discharged to a basin (18) from which it is pumped to a gas mixer and injector (21) into a floatation reactor (26); (b) a vessel (27) is located centrally at the base of the floatation reactor (26); (c) treated water is captured in the central vessel (27) which is open at the top and discharges through an outlet (31) in the floatation reactor (26) base; (d) floating residues are removed (36) from the floatation reactor (26) water surface; (e) the injector (21) gas pressure is greater than the water pressure; (f) the injector (21) funnels tangentially into and around the lower part of the floatation reactor (26), creating a rising two-phase circular current (29); (g) a biological water treatment and sedimentation chamber (13) is located between the car-wash (10) and the basin (18), and (h) the floating residues (36) are discharged to the chamber (13) through a filter.
